Application September 7, 1951, Serial No. 245,509 6 Claims. 01. 160-90) This invention relates to an improved storm window and screen assembly.

It is illustrated in a storm window and screen assembly adapted to be secured externally of and adjacent to a conventional window opening housing double-hung window sash. It is illustrated as embodied in an assembly composed largely of metal and preferably of relatively thin sheet metal of light weight.

As is illustrated in my co-pending application, Serial No. 245,510, filed September 7, 1951, the general features of this invention may be embodied in a permanent rather than a storm window and screen sash assembly.

An object of the invention is to provide a storm window and screen sash assembly embodying two storm window sashes and a screen sash, interchangeably hung in two upper pairs of opposed complementary sash guide channels and one lower pair of opposed complementary sash guidechannels.

Another object is to provide in such an assembly lower opposed sash guide channels whose inner walls are cut away for substantially their entire length to permit ready insertion or removal of the sashes for cleaning or the like.

Another object is to provide a storm window and screen assembly which is adapted to be secured to the outer face of a window opening housing the conventional double hung window sashes. The assembly is provided with inner lower sash guide channel walls which are cut away for substantially their entire length, and through which a lowered sash of the assembly may be tilted inwardly to rest against a partially raised or lowered sash of the double hung window. Such construction and operation of the assembly permits the so-called no-draft ventilation of the room and permits a window to remain open even during a rainstorm.

A meritorious feature is the provision of a sash gripping element overlying the bottom walls of the lower sash guide channels which element grippingly releasably holds the lower sashes in different raised position.

Other objects, advantages, and meritorious features will more fully appear in the following drawings, specification, and appended claims, wherein:

Fig. 1 is a front elevation of the storm sash and screen assembly with two storm sashes and a screen sash mounted therein with the interior storm sash partially raised, as would be seen from outside the building;

Fig. 2 is a back elevation as would be seen from the interior of the building;

Fig. 3 is a cross-sectional view of the assembly taken on line 3-3 of Fig. 2;

Fig. 4 is a cross-sectional view of the assembly taken on line 4--4 of Fig. 2;

Fig. 5 is an enlarged sectional view of the intermediate upper'sash guide channel wall shown in Fig. 4;

Fig. 6 is an enlarged sectional view of the lower sash gripping element shown in Fig. 3;

Fig. 7 is a broken perspective view of the header, jamb, and sash portion of the assembly;

'ice Fig. 8 is a cross-sectional view of the header, sill, and jamb members taken on line 8-8 of Fig. 7;

Figs. 9, 10 and 11 are cross-sectional views of the header, sill, and jambmembers with two storm and one screen sash mounted therein disposed in different positions within the assembly;

Fig. 12 illustrates the positions of the storm and screen sashes, with the latter dropped back to the no-draft position with its upper rail resting against one of the double-hung permanent window sashes.

The storm sash and screen assembly is adapted to be secured to the exterior face of the usual permanent window opening having jamb, header, and sill members respectively indicated as 20, 22 and 24 in the figures, and housing double hung, vertically slidable, upper and lower permanent sashes 26 and 28.

The assembly is formed of sheet metal and comprises a rectangular frame having a header member 30, opposed jamb members 32, and a sill member 34 all connected in a convenient manner at their overlapping corners. The header, as shown in Fig. 7, is generally channel-shaped in cross section with two downwardly extending flanges 36 and 38 folded upwardly as at 40 and 42. Flange 38 is bent inwardly of the frame, as is shown in Figs. 8-12. An upwardly extending folded flange 44 of the header overlies the header 24 of the permanent window opening and is secured thereto by screwsor the like, as at'46, as shown in Fig. 1. p 1

The sill 34 of the rectangular frame shaped as shown in Figs. 7-12 of the drawings, has a lower flange 48 adapted to seat upon the sill 24 of the permanent window opening. An inner wall 50 spaces a bottom wall 52 above the permanent sill 24. A folded raised lip portion 56 is adapted to bear against a lowered sash, as shown in Figs. 9, 11 and 12.

The jamb members .32of the assembly are generally Z-shaped in cross section, as shown in Figs. 3, 4, 5 and 6. The exterior leg of the jamb is folded back upon itself along its entire length to provide an outer wall 58 for upper and lower sash guide channels hereinafter to be described. The Z-shaped jamb members have a jamb face 60 spacing outer wall 58 from an inner folded flange 62. Said flange is adapted to overlie the exterior face 20 of the permanent window opening and be secured thereto by screws 46.

Fig. 5 shows a generally Z-shaped intermediate wall formed of thin sheet metal having one leg 64 grippingly telescopically received within the folded flange 62, another leg 66 upstanding from the jamb face 60 of the'jamb members, and a bottom wall 68 spacing apart said legs and approaching jamb face 60 at an acute angle. This intermediate wall is disposed within the upper half of the rectangular frame cooperatively forming an upper exterior sash guide channel with aforementioned flange 58 and body portion 60 of the jamb members.

An inner guide channel wall 70 is grippingly telescopically received within folded flange 62 and adjacent leg 64 of the intermediate wall. This inner wall extends a greater distance down the edge of the jamb members than does the intermediate wall, and overlaps the upper portion of a sash in a lowered position within the frame, as shown in Figs. 9 and 11. This inner wall, upstanding leg 66, and bottom wall 68 of the intermediate wall, form an inner sash guide channel. This inner wall is bent slightly inward of the frame, as at 72, to grippingly engage the faces of side rails of a sash mounted in said inner channel.

Overlying jamb face 60 and extending from the sill member bottom wall 52 to the lower end of the intermediate wall is the lower opposed complementary sash gripping strips 74 generally L-shaped, as shown in Figs. 3 and 6. Said strips have a leg 76 telescopically gripingly received within folded flange 62 of the jamb me bers. Another leg -78- bent. inwardly of the frame and overlying jamb face 60 approaches said face at an acute angle. These sash gripping strips serve the double-function of-providing a seal between the jamb members and sashes in the loweF-guide channels, and serve also to cooperatively grippingly hold a sash -in diflerent raised positions mounted-- in th'e lower-"guide channels. I

Two storm and one screen sash are generally used with this assembly and indicated in the figures as A;B, and C, respectively.- Theyare mounted interchangeably within the guide channels for vertically-' slidable movement. To mount the sashes in the frame, as shown inthe figures, the upper-rail of -the'sash to be mounted in the upper exterior guide channel is inserted in the lower half of the frame between the opposed 'sashigripping strips 74. The sash is 'then elevated andithe upper rail guided into the upperexterior guide channel. The lower rail is then swung into the :frame between theiop posed gripping strips 74, and the sash fully elevated. -It is held in its elevated position by the'cooperative gripping action of the exterior walls and the upstanding leg 66 of the intermediate walls. Av second -saslr may be inserted within the frame inthe samemannerand allowed to rest in the lower sash guidechannel. It is' held against transverse movement by-the cooperative gripping action of the opposed complementary sash grippingzstrips 74. The third sash may be-inserted withinthe frame in a similar manner and may be allowed tcurest in either the upper inner sashguide "channels, "or inthe lower sash guide channel, as in Figs. 9 and 11 respectively. :If in the elevated position,- as in Fig; 11;, it is held'in such position by the cooperative gripping action ofu'nner wall 70 and the upstanding leg 66 of the intermediate wall. The opposed complementary-bottom walls-78 of the intermediate walls cooperatively.grippinglyengage the edge of the sash and assist in holding it in= the elevated position. i

As will be seen in Figs. 9, 11 and 12,. the sash indicated as Ahas a sash meeting rail 'with a downwardly extending lip 80 adapted to overlap'the' top .rail of the subjacent sash. Such overlapping of-themeeting rails form a weatherproof seal therebetween.

Fig. 12 illustrates the positions of :the sashes to provide a no-draft ventilation of the room. Storm sash A is mounted in the upper exterior sash guide channels. The screen sash C is mounted in the lower sash guide channels. The lower rail 82 of storm sash C is inserted within the lower sash guide channels and allowed to rest upon upstanding lip 56 and bottom wall 52. The upper rail 84 is allowed to rest against the partially lowered permanent upper window sash 26. With the sashes in such position air may enter the room through the assembly, as is indicated by the arrows.

If the assembly is installed with a permanent window opening whose upper double hung sash, when elevated, will permit the upper rail of storm sash B to pass thereunder, then said upper rail of the storm sash may rest against the lower double hung window sash 28. If sash 28 is then partially elevated the air will pass thereunder instead of as shown in Fig. 12.
